VAPORIZING DEVICE FOR GAS-ENGINES.

79 all whmn it Hui/y concern:

Be it known that I, J ACOB LAGRANGE ASH, of the city of Lansing, in the county of Ingham, in the State of Michigan, have invented certain new and useful Improvements in Gas- Engines, of which the following is a specification.

My invention relates to improvements in gas-engines; and the object of the invention is to devise an improved means for insuring a perfect mixture of gasolene and air entering the explosion-chamber; and it consists, essentially,of a mixing-chamberformed in the body of the intake valve and having the air-pipe leading from the base of the engine into the valve-body directly below the valve proper, a branch of the air-pipe extending up to the mixing-chamber, and a suitable reservoir for gasolene being provided at the top of the mixing-chamber, from which the gasolene is delivered in a small stream at the top of the chamber, and the parts being otherwise constructed and arranged in detail, as hereinafter more particularly explained. Figure l is a perspective view of portion of a gasolene-engine to which my invention relates. Fig. 2 is a vertical section through the major portion of Fig. 1, parallel with the cylinder.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the cylinder of the gasolene-engine,and B the valve casing or body.

0 is the passage-way above the valve, leading into the explosion-chamber at the end of the cylinder.

D is the valve, having a seat at b andprovided with a stem 0, extending through a spider c in the orifice O. The valve D is held on its seat by the spiral spring d, extending between the spider c and the collard on the end of the valve-stem c.

E is the mixing-chamber, connected by the passage-Way e to the space D, immediately below the valve D.

F is the pipe for the admission of air, which is connected by a branch F to the valvechamber and a bent extension F to the mixing-chamber intermediate of its length.

G is the drain-pipe for the mixing-chamber, which is designed to carry back to the tank all surplus gasolene.

H is a small gasolene-reservoir which is kept supplied with gasolene by a pump, the reservoir being connected to the mixing-chamher by a valve h, which is intended to deliver a small stream of gasolene at the top of the mixing-chamber, allowing it to fall down through the mixing-chamber to the bottom. At the time of suction in the engine part of the air will pass around through the bent portion F of the pipe, and thence pass directly across the falling stream of gasolene from the reservoir H, which it vaporizes and carries With it enough gasolene to form a proper mixture. When the valve is opened by suction, this mixture passes through the passage-Way G into the interior of the engine, Where the explosion takes place.

I find in practice that the air passing through the mixing-chamber in the manner hereinbebefore described and carrying with it gasolene serves to thoroughly vaporize it and forms a proper mixture suitable for the most efiicient Working of the engine.

What I claim as my invention is 1. In combination, a cylinder, a casing, a passage leading to the cylinder, a valve controlling the same, a gasolene-supply, a mixing-chamber, air-passage leading directly across the ,mixingchamber and a second airpassage leading through the casing and intersecting the passage from the mixing-chamber below the valve, substantially as described.

2. In combination, a cylinder, a casing, a passage leading to the cylinder, a valve controlling the same, a gasolene-supply, a mixing-chamber, air-passage leading directly across the mixing-chamber and a second airpassage leading through the casing and intersecting the passage from the mixingchamber below the valve and a return-pipe leading from the mixing-chamber to the gaso1ene-supply, substantially as described.
